Benefits of technology

This patent is about a spray that can be used on fruits, like cherries, to prevent stem end rots. The spray can be applied pre-harvest or after harvest. The spray results in low levels of residue in the crop, which are well below safety standards for food. This helps to ensure that the spray is safe for use and doesn't affect the quality of the crop.

Problems solved by technology

Pathogen infections can result in significant losses to agricultural crops caused by pre-harvest damage, killing them outright or weakening them so as to decrease yields and render the plants, fruit or grains susceptible to primary and secondary infections.
Post-harvest infections also results in significant loss of agricultural products during storage, processing and handling.
Many pathogen treatments may produce residues, although very small, leave the treated product in breach of the law of the country to which it has been exported.
Further, some current treatments also result in harm to select beneficial microorganisms present on the surface of the crop.

example 1

ON OF THE DRY FORMULATION

[0113]25 kg of sodium metabisulphite is combined with 67 kg of a sodium benzoate powder and then 1 kg of Diacel 150 (CAS #9000-34-6) is further added. The resulting mixture is then blended by addition to a cement mixer. The resulting mixture is then blended by addition to a cement mixer (100 L capacity revolving drum mixer with a 880 W 1440 RPM electric motor). The mixture is blended for 10 minutes, allowed to stand for 10 minutes and further blended for an additional 10 minutes. The described process provides 93 kg of the dry composition.

ON OF A FORMULATION COMPRISING A SURFACTANT

[0114]To 93 kg of the dry composition is added 5 kg of polyethylene glycol and the resulting composition is blended by addition to a cement mixer (100 L capacity revolving drum mixer with a 880 W 1440 RPM electric motor). The mixture is blended for 10 minutes, allowed to stand for 10 minutes and further blended for an additional 10 minutes. The described process provides of 98 kg of the desired formulation.

[0115]40 g of the pre-prepared formulation is added to 10 L of water and mixed with agitation and the resulting dispersion is allowed to stand for 10 minutes to ensure the powder formulation is dissolved.

FOR DILUTED ‘DRY COMPOSITIONS’

[0116]Preparation of Products

[0117]WOB NP 1 and WOB PH1 were prepared according to the general method of Example 1, wherein sodium sulphite is substituted for sodium metabisulphite in the case of WOB PH 1. The method of Example 1 was further modified whereby the sodium benzoate added was in the form of a prill bead rather than a powder.

[0118]The water used throughout the projects is rainwater held in the dark in a plastic tank with stable pH value of 6.25. Controls were set up by replacing actives with tank water only.

[0119]Products were dissolved in tank water before application to the agar plants. Tank water (pH 6.25) was adjusted to the respective pH levels prior to adding the actives to determine the change in pH caused by the actives.

[0120]Tank water was adjusted to pH 4.0, 5.5, and 7.0 before adding sodium benzoate, sodium metabisulphite and WOB NP1, each at 0.8%.

[0121]Tank water was adjusted to pH 7.0, 7.5 and 8.4 before adding sodium benzoate, s...

Abstract

The present invention provides a method for treating crops in field or in a processing facility comprising the steps of producing a dry composition comprising a metabisulphite, a benzoate salt and a cellulose additive; preparing said dry composition as a formulation; and applying the formulation to a crop, wherein said treatment is for prevention or reduction of crop damage by plant pathogens, or reduction of bacterial, fungal or human pathogens.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a method of the treatment of crops and more particularly a method for preparing and applying a formulation, preferably in the form of a spray to the growing crop, for control of pathogen growth and to provide crop protection from pathogenic attack. The formulation may also be applied as a fruit and vegetable wash to remove harmful pathogens from surface of produce and extend shelf life and safety of the packed or stored produce as a post harvest application.BACKGROUND OF THE INVENTION[0002]Pathogen infections can result in significant losses to agricultural crops caused by pre-harvest damage, killing them outright or weakening them so as to decrease yields and render the plants, fruit or grains susceptible to primary and secondary infections. Post-harvest infections also results in significant loss of agricultural products during storage, processing and handling.[0003]When fruit, vegetables and grains are to be eaten or pr...
